Comment 1 Dario Andres 2009-05-07 02:33:39 UTC 
What is your Phonon version ? Thanks
Comment 2 miki 2009-05-07 02:39:16 UTC 
I compile kde from trunk and update every night so ...
Comment 3 Dario Andres 2009-05-07 02:41:38 UTC 
But do you also compile kdesupport/phonon ? or do you use a global packaged version ? (that may be a possibility too)
Thanks
Comment 4 miki 2009-05-07 02:45:13 UTC 
Phonon Version: 4.3.50 . of course ? I can not run beta1 4.3 without kdesupport?
Comment 5 Dario Andres 2009-05-17 20:15:53 UTC 
What Phonon backend do you use ? Thanks

Comment 10 Myriam Schweingruber 2010-02-10 10:45:22 UTC 
Is this still valid with KDE SC 4.4?
Comment 11 Myriam Schweingruber 2010-03-18 22:29:37 UTC 
I can't reproduce this here, using KDE SC 4.4.1
Comment 12 Myriam Schweingruber 2010-09-17 12:38:51 UTC 
I was just able to reproduce this crash with the VLC backend (version 0.20 stable) instead:

Comment 13 Jean-Baptiste Kempf 2010-10-17 19:56:20 UTC 
I am worried, because I don't see any phonon-VLC or VLC in this backtrace.
Comment 14 Myriam Schweingruber 2010-10-17 21:39:48 UTC 
It is not backend related.
Comment 15 Harald Sitter 2010-12-18 15:02:23 UTC 
<apachelogger> comment 8 and 12 are fundamentally different crashes
<apachelogger> #12 comes probably from VLC not implementing a streaminterface
<apachelogger>     Q_ASSERT(streamInterface);
<apachelogger> relevant line of code ^

It is arguable whether Phonon should assert there, but not related to the original report...

Is the original issue still reproducible?
Comment 16 Myriam Schweingruber 2010-12-19 23:43:19 UTC 
Changing status.
Comment 17 Myriam Schweingruber 2013-04-13 06:21:18 UTC 
Closing for lack of feedback. Please feel free to reopen if you can reproduce this with KDE 4.10.2 or later.
